Its best not to get expectations up for these stand-alone things. It is apparent that Disney is going to be shitting out SW movies left and right so prepare for some stinkers. This is their answer to the Marvel Cinematic Universe, that's becoming plain as day.
Don't get me wrong, I'm hopeful. If these stand-alones about Fett, Yoda, Han are on par with shit like the Thor and CA movies then we all win. But right now I'm just hoping at least 7/8/9 are well done and see what happens with the stand-alones. My gut tells me the first stand-alone will be good, second ok, and then devolve into shit.
Hopefully I'm wrong and Disney follows Marvel's lead in quality as well as quantity. I don't think anyone can blame me for being skeptical though.
